The taskbar provides a location for programs and hardware devices to display icons. For example, if your computer supports advanced power management (APM), a Battery Meter icon can appear on the taskbar. When you close it last you should see your volume icon disappear. It is best to clost it manually rather than taking it out in the registry, otherwise you may find a future problem when you install some software that tries to place an icon in systray. I generally have not had a problem leaving systray open, as long as you close all other items that are running in systray. Rather than CTRL-ALT- DEL try single clicking or right clicking on each item and closing them that way. I always close everything running in systray before writing a CD but generally leave everything (I don't have a lot in there anyway) running during Logic without problems. Regards, Phil
